I
tried their data last week and found some shortcomings. These
shortcomings, of course, may not affect you.

size=2>1. They say "1970", but many stocks don't have data prior to 1990
even though they were trading.
<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff
size=2>2. They don't have de-listed stocks.

<FONT face=Arial color=#0000ff
size=2>3. They don't have the ability to give you actual as well as
split-adjusted data.

I
would suggest that you look at Reuter's Datalink and CSI
UnfairAdvantage.

<FONT face=Arial color=#0000ff

than CSI (1980). CSI, of course, does include de-listed
stocks.

They
both have the ability to give you actual prices and volumes for filtering
purposes. If you decide on Reuter's and you want access to actual data,
get back to me as I have a patch that will allow you to do
so.

Reaserch quality historical data sourceI am looking
for high quality data source to back test my systems. This link looks
pretty good: <A
href="">http://www.price-data.com/eod_stocks.cfm.
Their data seems to have unlimited number of decimals, such as 0.62387495.
This is very important for accurate back testing. Their price $199 for all
US stocks starting 1970 seems the best I can find. (3 CDs)Does
anybody have experience with their data (S&C research)? Or any other
data sources recommended? I know Yahoo Finance has histical data, but the
downloading and converting seems complicated and their don't have data for
inactive stocks (such as Netscape), which are of great value from a best
testing standpoint.- M.T.Send
